Marla Frazee could draw a book about folding laundry and I would read it. She reminds me of Jan Ormerod, whose 101 Things to Do with a Baby is out of print, but which I find used copies of for all my friends who get babied-up (and which does contain an illustration of folding laundry, come to think of it).
Anyway, Walk on! is So Much Fun. From the typography to the expressions on the baby's face, it is clean and funny and sly. The fact that it would also work for anyone embarking on a life change, like a college graduate or a person just getting divorced, is a mind-blowing bonus.
